GuideStar receives all information on 501c organizations from the IRS on a monthly basis. As of our October 9th update from the IRS Spectacular Stud Museum is not appearing on IRS Business Master File. You would need to contact the IRS to find out why this organization is not listed. You may contact the Nonprofit Division of the IRS for more information at: (877) 829-5500 (toll-free number). The IRS call center is open 8:00 am to 5:00 pm Eastern Time. Once the IRS updates the Business Master File, we will receive that update from the IRS. Because this information comes from the IRS we are unable to change or alter this information.

Please let me know if you need any further assistance or have any other questions.
